A User Profits $34,000 by Interfering with Weather Sensors to Manipulate Polymarket's Temperature Prediction Market

Odaily News A user profited $34,000 in the Polymarket weather prediction market by interfering with a weather sensor at Paris Airport. Polymarket previously used data from a Météo France sensor near Paris Charles de Gaulle Airport for settlement. The user purchased temperature options that were significantly higher than market expectations at a very low price. Subsequently, the user used a portable heat source to warm the sensor, causing the readings to spike sharply within a short period and be recorded as the day's highest temperature. This behavior occurred twice, on April 6th and April 15th. Météo France has now detected the anomaly and filed charges.
